IMPORTANT NOTICE
The following instructions must be observed at all times in order to prevent personal injury and physical damage to equipment and surroundings.
The instructions are classified according to the degree of danger or damage which may occur if the product is used incorrectly.
DANGER
Failure to follow the instructions will result in death or serious injury.
WARNING
Failure to follow the instructions could result in death or serious injury.
CAUTION
Failure to follow the instructions could cause personal injury or physical damage to equipment and surroundings.
IMPORTANT NOTICE
•
This dealer’s manual is intended primarily for use by professional bicycle mechanics.
Users who are not professionally trained for bicycle assembly should not attempt to install the components themselves using the dealer’s manuals.
If any part of the information on the manual is unclear to you, do not proceed with the installation. Instead, contact your place of purchase or a local
bicycle dealer for their assistance.
•
Make sure to read all instruction manuals included with the product.
•
Do not disassemble or modify the product other than as stated in the information contained in this dealer’s manual.
•
All dealer’s manuals and instruction manuals can be viewed on-line on our website (http://si.shimano.com).
•
Please observe the appropriate rules and regulations of the country, state or region in which you conduct your business as a dealer.
For safety, be sure to read this dealer’s manual thoroughly before use, and follow it for correct use.

TO ENSURE SAFETY
TO ENSURE SAFETY
WARNING
•
Be sure to follow the instructions provided in the manuals when installing the product.
It is recommended to use genuine Shimano parts only. If parts such as bolts and nuts become loose or damaged, the bicycle may suddenly fall over,
which may cause serious injury.
In addition, if adjustments are not carried out correctly, problems may occur, and the bicycle may suddenly fall over, which may cause serious injury.
•
Be sure to wear safety glasses or goggles to protect your eyes while performing maintenance tasks such as replacing parts.
•
After reading the dealer's manual thoroughly, keep it in a safe place for later reference.
Be sure to also inform users of the following:
•
Intervals between maintenance depend on the use and riding circumstances. Clean the chain with an appropriate chain cleaner regularly. Never use
alkali based or acid based solvents, such as rust cleaners. If those solvents are used the chain might break and cause serious injury.
•
Check the chain for any damage (deformation or crack), skipping, or other abnormalities such as unintended gear shifting. If any problems are found,
consult a dealer or an agency. The chain may break, and you may fall.
NOTICE
Be sure to also inform users of the following:
•
For SHADOW RD+, be sure to check that the plate unit cover and the plate unit cap are installed before riding the bicycle.
•
If gear shifting operations do not feel smooth, wash the derailleur and lubricate all moving parts.
•
If looseness in the links is so great that gear shifting adjustments cannot be made, replace the derailleur.
•
Products are not guaranteed against natural wear and deterioration from normal use and aging.
•
For maximum performance we highly recommend Shimano lubricants and maintenance products.
For Installation to the Bicycle, and Maintenance:
•
Depending on the shape of the frame, the rear derailleur may interfere with the chainstay.
•
Grease the inner cable and the inside of the outer casing before use to ensure that they slide properly.
Do not let dust adhere to the inner cable. If the grease on the inner cable is wiped off, the application of SIS SP41 grease (Y04180000) is
recommended.
•
Use an outer casing [OT-SP41] and a cable guide (SM-SP17/SP18) for smooth operation.
•
Use an outer casing which still has some length to spare even when the handlebars are turned all the way to both sides. Furthermore, check that the
shifting lever does not touch the bicycle frame when the handlebars are turned all the way.
•
If gear shifting adjustments cannot be carried out, check that the rear dropouts are aligned. Check whether the cable is lubricated and clean, and if
the outer casing is too long or short.
•
Periodically clean the derailleur and lubricate all moving parts (mechanism and pulleys).
•
Depending on the model, the guide pulley has arrows on it to indicate the direction of rotation. Install the guide pulley so that the arrows are
pointing counterclockwise when looking at the outer side of the derailleur.
•
If you hear abnormal noise as a result of looseness in a pulley, you should replace the pulley.
The actual product may differ from the illustration because this manual is intended mainly to explain the procedures for using
the product.

Chain derailment prevention plate
NOTICE
The rear derailleur plate assembly is equipped
with a pin or plate that prevents the chain
from derailing.
When passing the chain through the rear
derailleur, pass it through the rear derailleur
body from the side of the chain derailment
prevention plate as shown in the illustration.
If the chain is not passed through the correct
position, damage may be caused to the chain
or rear derailleur.
